The global credit crunch of 2008 and related sub-prime mortgage crisis of 2007 have made credit ratings agencies (CRAs) the focus of international attention. In particular, the quality of ratings information and the responsibilities CRAs owe to financial markets have come under intense scrutiny. Specifically, commentators, politicians, and regulators have expressed concern at the involvement CRAs might have had in creating global financial instability. However, the term ratings quality remains largely absent from the academic literature.This paper constructs a measurement instrument to capture ratings quality provided by CRAs, and assesses differences in perceptions of ratings quality amongst four stakeholder groups in public debt markets. Two macro-constructs of ratings quality are identified, labelled Technical Qualities and Relationship Qualities. The two macro-constructs are measured by ten micro-attributes, labelled: Cooperation; Independence; Internal Processes; Issuer Orientation; Methodology; Reputation; Service Quality; Shared Values and Norms; Transparency; and Trust. Each micro-attribute is operationalised into individual items, and then empirically tested using data obtained in the UK from 121 issuers, 75 non-debt issuing financial managers, 90 investors, and 120 other interested parties.The data suggest that ratings quality involves, in order of importance: the CRA's reputation; those values and norms of the CRA shared by users; the methodologies employed by the CRA; the independence of the CRA; and internal processes within the CRA. Multivariate analysis of variance finds no statistically significant variation between the groups for Technical Qualities factors. However, issuers rate Relationship Qualities and its micro-attributes of Trust, Issuer Orientation, and Service Quality higher than other market participants; a finding that reflects the dyadic relationship between the issuer's treasurer and lead analyst of the CRA. The paper concludes with a number of policy-relevant issues.  相似文献

This study investigates the effect of website stimuli on positive attitude and intentions to visit and recommend, through three emotional responses (pleasure, arousal and dominance). The model was tested regarding three island‐related websites. Findings show the role of emotions as mediators between website quality attitude and intentions. Arousal and dominance are revealed to be more important in the formation of a positive attitude than pleasure. Visual appeal and ease of use, followed by information, seem to be the most important components in forming a perception of the islands' website quality.

In this note, we highlight an important consideration of Larry Moss's life's work, the continual struggle within economics against racism. Larry initiated and supported the symposium on eugenics published by the American Journal of Economics and Sociology in July 2005. He edited the volume Social Inequality, Analytical Egalitarianism and the March Toward Eugenic Explanations in the Social Sciences in August 2008. These constitute obvious signs of Larry's concern.
He conjectured that the Trinity College Dublin political economists who held the Whately professorship should be thought of as a school. Such a school was in fact identified in 1850 by an outsider who pointed to their shared opposition to racial explanations within an institutional setting. That shared opposition allowed them to speak against the narrow interests of the rulers of the country. Of course, other political economists of the time, Mill in particular, were also emphatic in their anti-racism. Thus, not only do we need to take up Larry's challenge to describe the Trinity College school but we must also seek its connections with the Scottish-English group of anti-racists.  相似文献

This study examines the private consumption benefits of sports attendance using revealed and stated preference data from 28 Football Bundesliga teams across three divisions. Survey respondents were presented with positive (sporting success) and negative (management failure) scenarios and asked for the number of game trips if each scenario occurred. The results of a pooled random effects Poisson model show that travel costs and ticket price have a significant negative effect on the number of home game trips. The weighted consumer surplus per game trip including travel costs and ticket prices is €345. Consumer surplus per game trip was found to change by €41 (first division) and €98 (second and third division) if the positive scenario occurred and by €39 if the negative scenario occurred.  相似文献

Communication in the media regarding a potential avian influenza epidemic can serve to accurately and effectively inform the public OR misinform and contribute to unnecessary public panic and subsequent undesirable responses. Governments have time to develop communication strategies and specific messages that can effectively convey desired information at different stages of the anticipated pandemic. Effective social marketing incorporates the concepts of formative research, audience segmentation, and consumer focus. Based on the findings from earlier research on public awareness and understanding of bird flu, the collaborators of the project developed evidence-based advertising messages for two primary time-points in pandemic preparation and tested in a series of focus groups; modified them based on the findings; and then re-tested the final campaign. These findings provide important recommendations for the development of future social marketing campaigns in the event of pandemics or other public health crises.  相似文献

This study develops and tests predictions regarding factors that influence early‐stage CEO evaluation. We suggest that contextual elements of the CEO succession process will influence the heuristics that directors employ to aid in their early evaluation of a CEO because traditional performance metrics, such as firm performance, are less diagnostic of CEO quality in the first years of their tenure. Broad empirical support for our theoretical arguments is shown in a sample of Fortune 1000 firms. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

In the past decade, tourism firms have become aware of the great benefits of maintaining a solid base of loyal customers. Because rural tourism is a relatively new phenomenon in some countries, the main antecedent of tourism loyalty remains infrequently studied in rural lodgings. In this work, a structural equations model is explored, with PLS technique, giving relevance to the interrelationships among image, quality, satisfaction, and trust and among these variables and the tourists' behavior variables. Instruments are identified and exploratory research was undertaken among rural tourists of the main rural lodgings in two border regions of Spain and Portugal. The results confirm image as a direct antecedent of perceived quality, satisfaction, trust, and loyalty for rural tourism, too. The analysis also confirmed that quality has a positive influence on satisfaction and loyalty, and trust has a positive influence on loyalty. Image is shown as a key factor to rural lodging managers. This study may help rural tourism managers to develop and implement effective relationship marketing strategies.  相似文献

We use techniques from network science to study correlations in the foreign exchange (FX) market during the period 1991–2008. We consider an FX market network in which each node represents an exchange rate and each weighted edge represents a time-dependent correlation between the rates. To provide insights into the clustering of the exchange-rate time series, we investigate dynamic communities in the network. We show that there is a relationship between an exchange rate's functional role within the market and its position within its community and use a node-centric community analysis to track the temporal dynamics of such roles. This reveals which exchange rates dominate the market at particular times and also identifies exchange rates that experienced significant changes in market role. We also use the community dynamics to uncover major structural changes that occurred in the FX market. Our techniques are general and will be similarly useful for investigating correlations in other markets.  相似文献
